Application filed November 14, 1918. Serial No. 800,938.

To all whom ct may 001mm Be it known that I, ALFRED BONOM, a citizen of France, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Bearing, of which the following is a clear, and exact description. My invention relates to bearings of the pedestal type, and has'reference more particularly to turbine shaftbearings.

An object thereof is'to provide a simple, compact'and 'eflicient bearing having means wllie'eby thejournal therein is automatically or e A further object of the invention is to provide a bearing that will accommodate concentric shafts adapted-to rotate in opposite directions and which will automatically oil the journals of both shafts.

A still further object of the invention is to provide a bearing wherein every portion of the journal, or journals, receives oil'eontinuously.

line 2-2, Fig. 1; Fig.3 is a lo I obtain the above ob'ects by'providi'ng a j ourrial box having p're erably a removable bearing seat, which seat is provided "with exterior and interior grooves inclined to the axis of the seat and communicating therebe'stween; and means for forcing oil through the journal box and about said seat.

The invention consists of the construction and combination of parts to be more fully described hereinafter and fully set forth in the claims.

Reference is to be had to the accompany ing drawin forming a part of this specification, in w ich like characters indicate corresponding parts in all the views and in which: I 1

Figure 1 is a longitudinal vertical section through a bearing embodying my invention for a' single journal; Fig. 2 is a section on 'tudinal vertical section of a bearing embo ying' my invention having a concentric shaft adapted to rotate in opposite directions; Fig. 4 is a section on line H, Fig. 3; and Fig. 5 is a development of the journal portion of the 'outer shaft.

Before proceeding to a more detailed description of my invention, it must be clearly understood that while the disclosure of the bearing structure is better adapted for use with turbines, the same can be as efliciently used for any other purpose.

Referring to the drawings, the journal box 7 is preferably formed of a single cast ginlet 9. The bore 8 is alsoprovided with diametrically opposite longitudinal grooves 11, one central with the inlet and'the other with the outlet of the bore:

. Fit ing snugly into the bore of the box 7 is a bearing seat '12 having the shape of a sleeve,the outer extremities 13 of which, are beveled and adapted to be engaged by rings- 14 provided at each end of the box 7 and adapted to be secured thereto in any suitable .way and whereby said bearing seat 12 is packed in said bore 8. It is understood that if the journal box 7 is formed in two parts, the bearing seat 12 can be also formed of two or. more parts. The exterior lateral surface 'ofthe bearing seat 12 is provided with a series of circular grooves 15 inclined to the axis of the bearing and interconnected therebetwee'n by means of longitudinal grooves 16 provided on the said outer surfaceof the bearing seat and extending sub of saidseat. The inner-lateral surface of -the seat-p 12 is also provided with circular grooves 17 inclined similarly to thegrooves =15 withrespect to the bearing axis. .The

iment with the exterior grooves 15, that is, Eeach inner groove is superposed by an exterior groove, and it communicates with its 'corresponding inner groove by means of apertures 18 provided at intervals between the grooves in the. body of the seat 12. The inclination of the grooves is such that the projection of opposite portions of ad acent grooves will slightly overlap each other. See Fig. 1, as shown in dotted line and indicated-by 03-11. This" provision permits the consecutive grooves tocover the entire surfaceof the journal 19 engaging the bearing surface of the bearing seat 12. The ends 1 of the bearing seat 12 are packed by means 101 stepped rings 20 secured in any suitable {way to the shaft 21 land whereby oil is prevented from leaking i at the ends of the bearing seat 12.

The oil is forced into the bore 8 through l a pipe 22 connected to the inlet 9 where it is 3 distributed in the longitudinal groove 11 of the bore and there rom to the circular stantially parallel'to the longitudinal axis {inner grooves 17. are made to be in alineadjacent the journal 19 llli grooves 15 lying across the said longitudinal groove 11. The groove 16 interconnectin the circular groove helps to distribute the oil forced into the box more uniformly between all the grooves 15. The oil, passing about the grooves 15 before it finds its outlet through the pipe 3i-connected to the outlet 10, passes through apertures '18 into the inner grooves 17, as the resistance to the flow of oil is such as to keep all the grooves flooded with oil.

In the modified form shown in Figs; 3, a

so formed as to cover Wlth Oll every point of and 5, the box 7 is provided with a bearing seat 12 sealed therein by rings 14', similar to those disclosed for the structure shown in Figs. 1 and 2. The ends of the bearing seat 12 are packed similarly by stepped rings 20., secured in this case to a hollow shaft 23. connected to one ofthe turbine rotors. The journal of thishollow shaft is provided with a series of longitudinal apertures 2d adapted to supply oilfrom the grooves 17 to the, journal 25 of the inner shaft 26, which bears in the said hollow shaft 23. The said apertures 24; in the hollow shaft 23 are so formed as to supply every point of said journal during its rotation With oil from the inner g 'ooves l7- The llow or tubular shaft 7 therein the fluid pressure, which is prevented from entering into the bearing-by the provision of a seal, in forming a circular groove 27 on the inner surface of the tubular shaft 23 adjacent the rotor portion. A disk 28 carried by the journal 25. engages said groove, the space formed between said groove and disk being such as to condense the fluid tending to pass therebetween and thereby form a seal, the excess of condensed liquid escaping through a series of apertut es 29 provided in the tubular. shaft 23 and leading to a circular stationary trough 3 formed'about the tubular shaft 2-3, the said trough being-provided with an outflow tube 31 to carry ofithe condensed fluid. The

flow of fluid to the bearing surface is fur-.

therresisted by the film of oil formed in the neck 33. The journal 25 secured to the shaft groove having-a 26 can be formed, if desired, similar to-the bearing seat 17. The oil is supplied to said box 7 in a similar manner to that described for the structure show-n in Figs. 1 and 2 by means of a pipe 22 and carried ed by means of a pipe 34L;

The bearing seats are prevented from to tation Within the bores; of the casing by the provision of a key secured in any suitable way to the bearing box and engaged by one of the longitudinal grooves of the hearing seat, connecting the exterior or circular grooves of said seat, as shown in Fig 2 by character reference 32, and in Fig. 4 by character reference 82'. The said hey does not need to extend through the entire length of the journal box but only adjacent the ends said box being connected to the rotor, carries ox and having;

moepea thereof, so as to facilitate the circulation of oil in said groove engaging'the key.

Having thus described my invention, I- claim as new and desire to secure by Letters Patent:
